Objective To investigate the surgery method for early spontaneous posterior interosseous nerve entrapment,to observe the postoperative efficacy in treatment,to evaluate the surgical outcomes,and to provide a foundation for clinical choice of reasonable operation scheme.Methods 21 cases of early spontaneous posterior interosseous nerve entrapment received operation. 1 3 cases (1 8 arms) were treated by neurolysis, and 8 cases (8 arms )were treated by nerve grafts with small vessels wrapping operation;all the patients were followed up for 10 to 20 months;the finger extensor muscle strength and metacarpophalangeal joint activity were evaluated. Results The lesion extensor muscles were part of the denervation changes.Neurolysis muscle strength:14 arms were excellent(82.35%),2 arms were good,1 arm was fair,1 case was lost;extensor function:15 arms were excellent(88.24%),1 arm was good,1 arm was fair,1 case was lost.Nerve graft muscle strength:6 arms were excellent(75.00%),1 arm was good,1 arm was fair;extensor function:7 arms were excellent(87.50%),0 arm was good,1 arm was fair.Conclusion Neurolysis can have a good efficacy in treatment of early spontaneous posterior interosseous nerve entrapment without obvious degeneration.When the severe degeneration of entrapment nerve happens,a nerve graft surgical treatment is needed.

AIM:To establish the analytical method for the fingerprint of Radix Pseudostellariae by HPLC-MS and to estimate the quality of Radix Pseudostellariae from different habitats. METHODS: Radix Pseudostellariae from different habitats were analyzed and the total ion current(TIC) chromatographic fingerprint were determined by HPLC-MS.Some characteristic peaks were identified preliminarily based on the MS spectra and literature data. RESULTS: HPLC-MS fingerprint of 10 main peaks was established preliminarily.It was found that a small number of samples differed from others obviously. CONCLUSION: The method is reliable,accurate and can be used for quality control of Radix Pseudostellariae.

Objective To explore the application of amide proton transfer (APT) imaging in differentiating glioma from treatment effect and to evaluate the diagnostic efficiency of the quantitative APT-related parameters.Methods A total of 23 patients (15 males, 8 females, age: 13-80 years) with 27 lesions who had underwent APT imaging in Tongji Hospital(Wuhan, China) from October 2014 to June 2015 were enrolled in this prospective study.The scan protocols were MRI normal plain scanning, diffusion WI, contrast-enhancement T1WI and APT imaging.Both the magnetization transfer ratio (MTR) and the relative MTR (rMTR) of lesions were manually measured by drawing ROI in the functional post-processing workstation.The results were compared with those of pathologic examinations and radiographic follow-up (≥3 months).Mann-Whitney u test was used to analyze the data.Results Compared with contralateral white matter, the primary gliomas (n=12) and recurrent gliomas (n=8) manifested hyper-intensity, while the treatment induced injuries (n=7) showed iso-or hypo-intensity.The difference of MTR between tumors and treatment effects was significant (102.78(101.93,103.84) vs 100.17(99.94, 100.63);z=-3.76, P<0.01), so was the difference of rMTR between tumors and treatment effects (3.92%(2.69%,4.67%) vs 0.47%(-0.79%,1.11%);z=-3.43, P<0.01).Both those two quantitative parameters exhibited excellent diagnostic performance with the AUC of 0.986 and 0.943.The sensitivity, specificity and accuracy of MTR were 100%(20/20), 6/7 and 96.3%(26/27) in the threshold of 100.68, while those of rMTR were 95.0%(19/20), 6/7 and 92.6%(25/27) in the threshold of 1.66%.Conclusions Combined with the routine MRI images, APT imaging can provide excellent qualitative and quantitative information in differentiating glioma from treatment effect.Both MTR and rMTR are helpful for the differentiation with high sensitivity and specificity and can be used as non-invasive imaging biomarkers in evaluating treatment effect of glioma.

Objective: To identify the risk factors for postoperative fatigue syndrome (POFS) in outpatients with painless gastroscopy. Methods: The outpatients received painless gastroscopy from October 2016 to February 2017 in our hospital were included in this study.The possible factors related to POFS were summarized by reviewing the relevant literature.The questionnaires were completed by the methods such as preoperative interview, intraoperative recording, and telephone follow-up.POFS occurrence, score and outcomes were evaluated.The patients were divided into POFS group (groupⅠ) and non-POFS group (groupⅡ) according to whether POFS occurred.The risk factors of which P values were less than 0.05 would enter the multivariate logistic regression analysis to stratify the risk factors. Results: Two hundred and forty-six patients completed this study.Sixty-nine cases developed POFS, and the incidence was 28.0%, the initial fatigue score was (5.2±2.4), and the duration of POFS was 3(9) h. The mean consumption of propofol (according to anesthesia time, mg/min) was an independent risk factor for POFS. Conclusion The mean consumption of propofol is an independent risk factor for POFS in outpatients with painless gastroscopy.
